business lose money = small bills
2. wrong decisions made
3. company could be prosecuted under DATA PROTECTION ACT 1998 if person makes some kind of loss.

VERIFICATION*checks that data is accurate- DOUBLE ENTRY = 2 people type in the same data, if identical, it is accepted.

:( they both may make the same mistakes, will go unnoticed (highly unlikely)

PROOF READING= fully checking what has been typed against original document.
